• This tube contains sodium citrate as an anticoagulant and first in the order of draw in the absence of blood cultures and is – used for collection of citrated plasma for coagulation studies.NOTE: After the tube has been filled with blood, immediately invert the tube 3-4 times to mix and ensure adequate anticoagulation of the specimen.It is imperative that the collection tube is filled with stated volume of blood. Under-filled tubes will result in falsely prolonged values due to dilution of plasma with anticoagulant; and therefore cannot be processed. For example, 3.0 mL collection tube must have 2.7 mL of blood to 0.3mLs of sodium citrate.
• When drawing with a butterfly needle, students’ must do a waste tube using a red glass tube.
